Am running sweeps in Spanish speaking Latin America (South and Middle America).
Propeller works fine.
Now I want to scale up my POP camps and am searching for further traffic sources.
To my surprise Zeropark does not work so well (little traffic & does not convert so well for these geos).
Have tried popcash, popads and self advertiser but could not get that much of traction.
What alternative traffic sources can you recommend?
You could try Adsterra, Clickadu, Advertizer.
